CHAPTER 20

CHEMICAL TEXTURE SERVICES PT 1 PERMANENT WAVING

QuestionAnswer
WHAT MAKES UP THE STRUCTURE OF THE HAIR? CUTICLE, CORTEX, MEDULLA
TOUGH EXTERIOR LAYER OF THE HAIR. CUTICLE
MIDDLE LAYER OF THE HAIR CORTEX
INNERMOST LAYER OF THE HAIR MEDULLA
THE SYMBOL pH REPRESENTS THE QUANTITY OF HYDROGEN IONS.
BASIC BUILDING BLOCKS OF THE HAIR AMINO ACIDS PEPTIDE BONDS AKA (END BONDS) POLYPEPTIDE CHAINS KERATIN PROTEINS
MADE UP OF LONG CHAINS OF AMINO ACIDS LINKED TOGETHER END TO END LIKE BEADS KERATIN PROTEINS
DISULFIDE, SALT, AND HYDROGEN BONDS THAT CROSS-LINK POLYPEPTIDE CHAINS TOGETHER SIDE BONDS
STRONG CHEMICAL SIDE BONDS FORMED WHEN THE SULFUR ATOMS IN TWO ADJACENT PROTEIN CHAINS ARE JOINED TOGETHER DISULFIDE BONDS
RELATIVELY WEAK PHYSICAL SIDE BONDS THAT ARE THE RESULT OF AN ATTRACTION BETWEEN NEGATIVE AND POSITIVE ELECTRICAL CHARGES (IONIC BONDS); THEY ARE EASILY BROKEN BY CHANGES IN pH, AND THEY REFORM WHEN THE pH RETURNS TO NORMAL SALT BONDS
WEAK PHYSICAL SIDE BONDS THAT ARE ALSO THE RESULT OF AN ATTRACTION BETWEEN OPPOSITE ELECTRICAL CHARGES; THEY ARE EASILY BROKEN BY WATER (WET SET) OR HEAT (THERMAL STYLING), AND THEY RE-FORM AS THE HAIR DRIES OR COOLS. HYDROGEN BONDS
A TWO-STEP PROCESS WHEREBY THE HAIR UNDERGOES A PHYSICAL CHANGE CAUSED BY RAPPING THE HAIR ON PERM RODS, AND THEN THE HAIR UNDERGOES A CHEMICAL CHANGE CAUSED THE APPLICATION OF PERMANENT WAVING SOLUTION AND NEUTRALIZER PERMANENT WAVING
ABSORBENT PAPERS USED TO CONTROL THE ENDS OF THE HAIR WHEN WRAPPING AND WINDING HAIR ON THE PERM RODS. END PAPERS
WHAT ARE THE THREE DIFFERENT BASE PLACEMENTS THAT ARE USED WHEN WRAPPING A PERM? ON-BASE HALF-OFF-BASE OFF-BASE
REFERS TO THE ANGLE AT WHICH THE ROD IS POSITIONED ON THE HEAD; HORIZONTALLY, VERTICALLY, OR DIAGONALLY BASE DIRECTION
ONCE IN THE CORTEX, THE WAVING SOLUTION BREAKS THE DISULFIDE BONDS THROUGH A CHEMICAL REACTION CALLED REDUCTION. A REDUCTION REACTION INVOLVES EITHER THE HYDROGEN OR THE REMOVAL OF OXYGEN. REDUCTION REACTION
A COLORLESS LIQUID WITH A STRONG, UNPLEASANT ODOR, IT IS THE MOST COMMON REDUCING AGENT IN PERMANENT WAVE SOLUTIONS. THIOGLYCOLIC ACID
ALKALINE AND IS THE ACTIVE INGREDIENT OR REDUCING AGENT IN ALKALINE PERMANENTS. AMMONIUM THIOGLYCOLIC

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
